hi friends I need a hash function to build a Unique serial number by mixing a request code and a user name request codes are strings like this: They are literally HEX codes of MAC mac addresses. "002314EFD000544AB05345300045675609782123C3254B312123D12312EE13123F123D123123E00000000E00000000E0000000E0000000E0000000E00000000E00000000" i want to create a function that mix together this request code with user name that user entered and create new serial number. What implications i have to satisfy to create such hash function in php? Thanks for any suggestion
